What is the difference between 12v Low Voltage and 120v Standard Voltage for Indoor Lighting?

This page will help you understand the difference between 12 Volt Low Voltage
Indoor Lighting Systems and 120 Volt High Voltage Indoor Lighting System.

Definition of 12v: Also known as LOW voltage. This voltage is achieved by "stepping down", reducing or in other words, converting standard 110/120v HIGH voltage into LOW voltage with the use of a 12v transformer.
Definition of 120v: Also known as HIGH voltage, LINE voltage, Standard voltage or 110v/120v/130v. This is the voltage that comes directly into most homes.

12v Low Voltage saves energy and is much safer, but utilizes a transformer which converts higher voltage (120v) electricity to 12v Low Voltage.

With 120v, no transformer is required and is not as energy efficient unless you are using fluorescent.
